The Skeletal System Flashcards
Extension describe
Movement that increased angle between the bones at a joint
Moving body part toward midline of the body
Adduction
A complete circle of the body
Circumduction
Pronation
Rotation of hand toward ground (pans down)
Rotation of the hand and forearm that causes hand to face up wards
Super nation
Dorsiflexion
Flex ion of the ankle pulls top of foot towards the tibia
A movement that decreases the angle between the bones at the joint
Flex ion
Plantiflexion
Ecmxtension of the ankle movement that moves top of foot from the tibia eg.pointing toes
Function of long bones
For movement
Eg.femur
Function of irregular bone
Site for muscle attachment
Function of Sesamoid bone
Protects tendons from friction
Eg. Platella
Top part of the spinal column
Cervical vertebrae
Thoracic vertebrate
Middle vertebrae
End part of spinal column
Lumbar vertebrae
Largest arm bone
Humerus
Blood function in the skeletal system
Red blood cells produced in bone marrow
Bones Protect?
Internal organs heart l,kidneys, lungs
Flat bones protect
Vital organs in the body
Ribs skull sternum
Abduction
Hint:taken away
Body part moved away from the midline eg, soccer goalie
The six main functions of skeletal system
Protection -vital organs
Movement –attachment surface for muscles
Support-provides framework
A platella is the only example of this type of bone
Sesamoid
